Question

Silicon forms a compound with chlorine with mass percentage of silicon as 20.8% and that of chlorine as 79.2%. Calculate the empirical formula of the compound.

Answer 1

Answer:

Explanation:The empirical formula of the compound formed is .

Solution:- Mass of Si = 5.6 g

mass of Cl = 21.3 g

Percentage of chlorine = 21.3/26.9 ×100 =79.2

Percentage of silicon 100- 79.2 = 20.8

So, the empirical formula is . SiCl3
